Wanting to buy HPS Nap Campaign, but hesitating

That site seems pretty inactive, its announced tournaments on the main page date from years ago! Maybe it is because the forum is invisible to non-members?

Rest assured that club is very active, recent things like the release of the new Peninsula title showed that it's still alive and kicking.
You should have no problem looking at the public sections of their forum, only thing you can't get into are the army specific forums(Allied Coalition / La Grande Armee).
